A 5c charge experiences a force of 40n when put at a certain location in space. What is the electric field at that location?
Answers
At this 'certain location', the field is 40/5 = 8 newtons per coulomb = 8 volts

A biconvex lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of R 1= 10cm and R 2 = 15cm. The lens is made of glass with index of refraction n=1.5. We will employ the convention that R 1 refers to the radius of curvature through wich light will enter the lens, and R 2 refers to the radius of curvature from which the light will exit the lens.Is this lens converging or diverging?What is the focal length of this lens in air?

Explanation:
Carbon dioxide is a naturally occurring greenhouse gas... An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat. This trapped heat leads to melting ice caps and rising ocean levels, which cause flooding.

If we have the straight line on the graph it means that the slope is always the same whereas the non-linear graphs has a variable slope that changes depending on your point in the graph.
To conclude - if your graph is not a straight line it has variable acc at many points.
Final answer:
A speed-time graph where the points do not form a straight line indicates that the object is accelerating in a non-uniform way, meaning its acceleration is changing over time.
Explanation:
If the plotted points on a speed-time graph do not form a straight line, this indicates that the object is accelerating in a non-uniform way. Instead of maintaining a constant rate of acceleration (represented by a straight line), the object's acceleration is changing over time. This could mean that the object is speeding up, slowing down, or changing direction. For example, a curved line might represent a car that starts off slowly, then accelerates rapidly before braking.

B. 22 Hz and 42 Hz
Explanation:
The beat is an interference pattern which occurs when two waves of slightly different frequencies meet each other. The beat is heard as a periodic variation, whose frequency (called beat frequency) is equal to the absolute value of the difference between the frequencies of the individual waves:
In this problem, we are told that 20 beats per second are produced, so the beat frequency is
Therefore, we must find the two waves which have a difference in frequency equal to this value, 20 Hz. Let's see each choice:
A. 38 Hz and 63 Hz --> --> NO
B. 22 Hz and 42 Hz --> --> YES
C. 47 Hz and 55 Hz --> --> NO
D. 18 Hz and 26 Hz --> --> NO
So, the correct choice is
B. 22 Hz and 42 Hz

Answer: The ice and shel are at the same temperature.
Explanation: Conduction happens when you have two objects at different temperatures touching each other, in this case, the temperature flows from the hot object to the cold one, until the equilibrium is reached (this means that both objects are at the same temperature). So, in order to conduction to happen, we need a difference in temperature and direct contact. So there are two options of the given that can be the answer: "There is no direct contact" In the sentence says that "the ice is placed on the freezer shelf", so we have direct contact between both objects. "The ice and shelf are at the same temperature" Here both objects are inside of the freezer, so we can expect that both of them are at the same temperature, hence, there is no conduction.

When light passes from one medium (water in this case) into another medium with a different refractive index (air), it follows the law of reflection and refraction.
The law of reflection states that the angle of incidence (the angle at which the light enters the second medium) is equal to the angle of reflection (the angle at which the light reflects back into the first medium), both measured with respect to the normal (a line perpendicular to the surface).
In this scenario, the diver shines light into the pond at a 10-degree angle to the normal. When the light reaches the air-water interface, some of it reflects back into the water. According to the law of reflection, the angle of reflection will be equal to the angle of incidence.
So, the correct answer is:
B) 10 degrees.
The angle at which the light reflects back into the water is 10 degrees, the same as the angle of incidence.
